Need simple advice on door jamb switch

[jtdesigns]

I want to replace my door jamb switch. Wildman told me napa can get them, but they aren't the exactly the same..

The jeep one has 2 connectors I'm thinking it's because it's not a ground switch like gm uses.

Neways here is the one listed at napa,,,

 

Is the jeeps a grounded circuit?

The left side door switch is a two contact normally open switch. It applies a ground to the interior lights from one contact; the other contact goes to the chime module (Lights ON alarm). The right side door switch is a single contact switch, it applies a ground to the interior lights only.

Yes, the Jeep door post switch is in the grounded side of the circuit, and completes the ground when the door is opened. There are actually two -- the passenger door should have a single contact, the driver's door should have two contacts.

Thanks guys!!! That makes sense, I didn't even think about the the buzzer...

NO.......Wildman don't buy from Napa, and he told you Advance has the door jamb switch :D

 

The switch is - GP Sorensen # JS39 $3.56

 

And it should be a stock item in the store. Advance store that is ;)

you can also get these switches at teamcherokee.com and wholesalemopar.com

I can locate the 2 contact door jamb switch (GP Sorensen JS39).  
Thanks Wildman!

 

But where do I find the passenger side single contact switch?

[AnotherOldJeepGuy]

From reading this thread, the passenger side is just 1/2 of the driver side.  So if you don't find the passenger side, seems like you could probably use the same switch, just only use two of the 4 contacts.  You can use an ohm meter to find two connections that are closed (connected, 0-ohms) before you depress the switch and open (disconnected, infinite ohms) when you press it.

 

If there are only 3 contacts on the driver side switch, then I would assume it uses a common ground connection.  The determination of which 2 contacts to use would be the same.

Well, this thread may be why my buzzer never worked, maybe I have the wrong switch on the drivers side, or the wires are wrong.  Thanks!!
